I have to disagree with you. I rebuilt my engine for performance. Certain sound restrictions through smaller pipes limit air flow and in turn my performance. My car can sound loud but at idle it is a low rumble. You tell me how to reproduce 500 pure HP without the rumble and I'll consider it. We don't all live in cities with small roads and tight traffic. Some of us live in the country where you can stretch what the car does
I think I live down the road from you. Watch out for me I am bent on revenge.
